He is born in Orléans, in Loiret, on July 26, 1952. Only sons of a family of the middle-class, he followed, in Puteaux (Hauts-de-Seine), a schooling without difficulty until the scientific baccalaureat. After having obtained this diploma, in 1969 with the Mention Assez Bien (Honours), Patrick Levaye carried out a preparation in agronomy and was acceptable with a veterinary contest. He decided, finally, to turn to studies of botany. He obtained its licence of botany.

Levaye, who wished to carry out a professional path in the public office, decided to present himself to the contest of the Regional Institute of French Administration (RIFA), which he makes a success of in 1975. Left graduate RIFA from Metz in 1977, Patrick Levaye carried out his military service (which was, let us recall it, at the time, obligatory) with Paris Fire Brigade. After his military service, he entered to the Minister of the Economy, Industry and Employment (France), with the Management of the Forecast, as attache with the Central Administration.

In 1982, he entered to the École nationale d'administration (ENA), in promotion "Leonardo da Vinci".
